I'm getting a NullPOinterException from org.hibernate.hql.ast.util.SessionFactoryHelper.findSQLFunction(SessionFactoryHelper.java:342)
on the query: SELECT Publication FROM Citation AS c WHERE c.enamelId = '0323' ORDER BY c.publication.year
Any idea if this is caused by (my) underlying user error?
Hibernate version: 3.2.0 GA, GA versions of annotations and entity manager on Glassfish 9.0_01 (build b14)
Mapping documents:
from Citation:
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(insertable=false, updatable=false)
private String pubId;
@Column(name="pieceAka", insertable=false, updatable=false)
private String enamelId;
private String changedby;
@ManyToOne(fetch=FetchType.EAGER)
@JoinColumn(name="pieceAka")
private Enamel enamel;
@ManyToOne(fetch=FetchType.EAGER)
@JoinColumn(name="pubId")
private Publication publication;
Name and version of the database you are using: MySQL 5.0
